FLUSHING SYSTEM FOR DRAINS AND SEWERS.

.To @ZZ whom it may concern:

Be it known that we, IIRAM 7. MUDON ALD and THOMAS lV. SHUNK, of Bucyrus, in the county of Crawford and State of Ohio, have invented a new and useful Improvement in Flushing Systems for Drains and Sewers, of which the following' is a specification.

This invention contemplates certain improvements in flushing systems for drains and sewers, having for its object to utilize the waste water from the various water-receptacles throughout a building or house, as also from any point upon and around or outside the building-as, for instance, a cistern or well-for cleaning out the drains and sewers; and to these ends the nature of the invention consists of asystem of waste-waterpipes leading to a common tank or receptacle which is adapted to permit its accumulated water or contents to be instantaneously discharged, and in certain details of construction, substantiallyas hereinafter more fully set forth, and pointed out in the claims.

In the embodiment of our invention we employ a tank or receptacle A, suitably disposed, say, at the head of the drain-pipe B, into which, at a common point a,- is received the waste water from the wastewater pipes O, D, E, F, and G, connecting with the various water-receptacles throughout a building or house and, with a cistern or well, or a conductor from roof of building or veranda. The connection between said tank or receptacle A and said pipes is effected, however, by means of a trunk-like pipe II, with one branch of which connects the pipe D, while with the main arm of which connects a similar but greater len gthened trunk-like pipe I. IVith the trunklike pipe I connect the pipes O, F, and G, the cistern overiiow-pipe F having a trap F', while with the pipe C connects the pipe E. The connection between the tankl or receptacle A and the drain-pipe B is made by means of a trap-pipe l5 and a coupling B2, and with the trap-pipe B connects a relief pipe J, which may connect with the roof of the house.

The tank or receptacle A has connection. above the water-line with the pipe J by an overflow-pipe J while with the same pipe J connection is also made for a drip-pipe J 2 for carrying off water from around the pipe J to prevent the displacement of the latter, as would occur from the action of frost that would form if no provision were made to carry off water at this point.

The tank or receptacle A is provided with a valve-seat K, which is formed with an annular conical ridge or elevation o adjacent to its outer edge or flange b', which is received between the lower end of the tank or recep tacle and the upper end of the coupling B2. This construction of valve-seat provides more especially for the water-tight packing of the joint formed by the connection of the valveseat with the tank and coupling, in that bctween the ridge or elevation b of said valveseat and the tank or receptacle A is furnished a space, which is filled in with a cement or other packing b2.

K is a valve, which is arranged within the tank or receptacle A, and is adapted to rest upon the seat K. This valve consists of a plate c, upon the under side of which is held a gasket or packing c by means of a spring disk or plate c2, which is held or adjusted in place by a screw c3, passing through said plate e2 and entering a central pendant c4 of the plate c. The valve K is provided with a stem or rod K2, which is connected thereto by a turn-buckle or swivel d. It consists of an elongated or elliptical frame or coupling, into the upper central portion of which is screwed the lower end of the stem K2, while its lower central portion has an aperture, through which loosely passes a headed pin d', which is screwed centrally in a concavity d2 in the upper surf-ace of the plate c of the valve K. The valve stem or rod K2 is provided with a handle e for its convenient manipulation, while immediately below the latter it is provided with a screw-threaded surface, as at e', the purpose of which will appear farther on.

In the upper part, near the top of the tank or receptacle A, is arranged a bracket or spider L, which is constructed as follows: f is a cross piece or plate, which is provided with apertures-one at each end-through which pass and to which are fastened by nuts the upper threaded ends of guide-rods M M, the lower ends of which are screwed into the valveseat K, while they pass bodily through apertures in the valve K to permit of the guiding of the latter thereby. Seated in and bolted to the center of the plateg or crosspiece f is abushing-like block f the aperture of which is screw-threaded to permit of the engagement therewith of the screw-threaded surface e of the valve rod or stem K2.

The plate or cross-piece f in a plane at right angles to the points of connection of the rods M therewith is stepped, as at f2, and upon its stepped portions carries segmental clamp-blocks f3 f3, which have swiveled thereto screw-bolts g g, screwing or working in the vertical portions of the plate f. Upon the screw-bolts g g are fitted nuts g g', by properly manipulating which the segmental clamp-blocks f 3 f 3 are thrown outward and caused to impinge against the inner side of the tank or receptacle A, and thus secure the bracket L in place. By reversing the movement of the nuts g g the clamp-blocks f3 f3 are withdrawn from the inner side of the tank or receptacle A, and then, by taking off the nuts at the upper ends of the rods M, the bracket L, together with the valve K and its stem or rod K2, can be removed, as is required in repairing or cleaning the parts.

The tank or receptacle A is iitted with a suitable cover A, which is provided with a hand-hold a', adapted to be let into a depression in said cover out of the way when not in use.

In operation it will be seen that upon the accumulation in the tank or receptacle A of the Waste water conducted from the various points, as above designated, thereto by unscrewing the valve rod or stem from the bracket L, which, when acco1nplished,\vill lift the coupling or frame d of the swivel or turnbuckle to the head of the pin'tl and permit of the subsequent sudden lifting or raising of the valve, and then by pulling upward the ers, the combination, with the waste-water pipes and drain-pipe, of the tank or recepvalve rod or stem the required extent the water in said tank or receptacle is suddenly and bodily discharged below, permitting it to pass into and flush out the drain-pipe. It necessarily follows as the water rushes on through and carries out all iilth from the drain-pipe it will enter the sewer with great force and volume, and by its action also clean out the sewer, and thus keep both the drain and sewer in good sanitary condition. In case of the failure to timely open the valve in the event of a rain or of the rising of the water above the water-line in said tank or receptacle provision is made for carrying off the overflow by the overiiow-pipe J', emptying into the pipe J, which will thus prevent the backing up of the water in the waste-water pipes.

It will `of course be understood that the tank or receptacle A has a greater holding capacity than the drain-pipe, being constructed of pipe suiiiciently large (if not supplied by length of pipe-line) to have the required holding capacity and about twice the area or diameter of the latter, having obviously in view the letting into the drainpipe at once upon the opening of the valve of the tank or receptacle (also in diameter about half that of the tank or receptacle) a volume of water greatly in excess of the area or crosssection of the drain-pipe, whereby the water is caused to enter the latter under a great head of pressure, and thus do its work with great efficiency and expedition.

Ilaving thus fully described our invention, what we claim, and desire to secure by Letters Patent, is-

l. In a flushing system for drains and sewers, the combination of the waste-water pipes, a tank or receptacle connecting with the drain-pipe, and a relief-pipe, also connecting with the drain-pipe and having an overflowpipe connection with the tank or receptacle, as also a drip-pipe, substantially as set forth.

2. In a flushing system for drains and sewers, the combination of the tank or receptacle A, the flanged coupling B2, and the valve-seat K, secured between the lower end of the receptacle and the coupling and provided with the annular conical ridge b adjacent to the outer edge or iiange b of the valve-seat and of slightly less diameter than the receptacle,
